Verbatim DatalifePlus 52x CD-R
Folks don't seem to review media very much anymore, but I've had good experience with the Verbatim DataLifePlus in 48x, this is the 52x version. "Pricegrabber":http://www.pricegrabber.com/search_getprod.php/masterid=987018 shows them with prices of $50 for 100 pieces since it is discontinued now. The Verbatim part number is 94594.
Instead, you can get the 50-pack version from "Pricegrabber":http://www.pricegrabber.com/search_getprod.php/masterid=699647/blsrt=1 which is part number 94523.
While you are at it, your can get "Fuji":http://www2.newegg.com/product/product.asp?item=N82E16817150121 jewel cases to put your CDs in for about $10/100 cases.
